Abstract: A base station function deployment control device includes a base station function deployment information acquisition unit configured to acquire base station function deployment information indicating a current base station function deployment in a radio access network of an open radio access network (O-RAN) specification via an interface with a service and management orchestration (SMO) function unit and a base station function deployment setting information transmission unit configured to transmit base station function deployment setting information indicating change content for changing the base station function deployment in the radio access network via the interface.

Abstract: A plurality of schedulers each corresponding to one or more slices perform, in a same cell formed by one RU, scheduling of radio resources for a UE that uses a corresponding slice. A RAN controller identifies, for each of a plurality of schedulers, an amount of radio resources required for each scheduler in a predetermined period T, based on an amount of data and a communication quality of wireless communication by the UE in the cell. The RAN controller further allocates, to each of the plurality of schedulers, the identified amount of radio resources and a margin of radio resources that can be used for the scheduling.

Abstract: A plurality of DUs have at least a radio resource scheduling function among functions of a base station and each correspond to one or more slices. The plurality of CUs are each connected between a different DU among of the plurality of DUs and a core network, and each has, among the functions of the base station, a upper layer function than a function that the DU has. A radio unit (RU) has at least a radio wave transmission/reception function among the functions of the base station, and is deployed at an antenna site. The RU is connected with a plurality of DUs, and a plurality of slices provided through the plurality of DU are provided in the same cell formed by the RU 30.
